This 24 volt AC fan control board is engineered for park model furnaces from Atwood, Hydro-Flame, and similar manufacturers. The board halts the fan motor 90 seconds after a third ignition attempt fails to detect flame, conserving battery power and preventing unnecessary cold-air circulation. Following a one-hour delay, the system retries the ignition cycle until manual thermostat reset.
